GIS detection systems for Transformers

Partial discharge testing is an essential, proven tool that can locate and identify flaws in the insulation of cables, bushings, windings, tap changers and a myriad of other assets and accessories. In the early stage of ageing of insulated materials, detection of deteriorating performance may be difficult to detect by traditional test methods.
